Abstract: ABSTRACT OF THE DISCLOSURE    A pipe connector including a main body having a stepped bore in one end for telescopic insertion over the end of a pipe, creating  a   stepped  annular  area  around  the  pipe.    A  slip retaining nut is threaded into the end of the main body around the pipe,  closing of f the stepped annular area.   Slips are carried in a tapered annular space between the nut and pipe, Prior to actuation, the slips are held up in disengaged position by shear pins.  A pair of metal seal rings is disposed in the end of the stepped annular area opposite the nut.  A pair of dual-acting, hydraulically actuated pistons is disposed in the stepped annular area between the metal seal rings and slips.  Hydraulic pressure actuates the upper piston to move upwardly to energize the metal  seals,  and the lower piston to move downwardly to actuate  the  slips  into  gripping  engagement  with  the  pipe.          Floating,  self-centering lock ring segments are wedged between the  pistons  by lockdown screws  to prevent the pistons  from backing out of energizing engagement. with the metal seal rings and slips.   The connector may be released by backing out the lockdown screws which retracts the lock ring segments, unscrewing the slip retaining nut and removing it and the slips, pulling out the lower and upper pistons, and sliding the main body off the pipe.   The metal  seals may then be replaced along with the elastomer seals or slips, as needed.

Filed: 1990-06-29
Abstract: ABSTRACT      This contraption is permanently attached to footwears in order to improve traction on slippery surfaces such as mud, grass, ice or snow and other superficially rugged surfaces. The use of the footwear with this contraption on smooth and fine surfaces such as floors, streets and concrete pavements will not be impaired or detracted because the device is adjustable to function also on such surface conditions. Unlike other shoes with immovable and permanent spikes or with fastener slip over shoes, this contraption when incorporated to ordinary shoes, can be adjusted instantly to retract or protract the spikes by moving  a lever at the under-middle portion of the footwear;  forward to retract the spikes when walking on fine and smooth surfaces or backward to protract the spikes down for better traction on slippery and rugged surfaces or vice versa. The gadget is incorporated to the footwear during its manufacture at a relatively nominal expense, costwise advantageous to the buying public.  The convenience and affordable cost to people of all ages will reduce if not totally prevent the slip-ping accidents of persons walking outdoors during winter in all countries with frozen climate. Likewise, combat soldiers, hikers, hunters, and golfers altogether will greatly benefit from its use.

Title: Insertion/extraction mechanism for blind pluggable modules
Inventor: FERCHAU JOERG U
IPC: H01R13/629
Filed: 1990-01-10
Abstract: (57) Abstract An insertion/extraction mechanism (2) is used to cause blind mateable electrical connectors (10) on an electrical module (4) to engage and disengage mating electrical connectors (12) in a housing (6) by forcing the module (4) to and from its fully in-serted position within the housing (6). The mechanism includes a U-shaped handle (14) pivotally mounted to the module at its ends through elastomeric sleeves (30). The sleeves (30) are each mounted in a mounting hole (32) in the module (4) and each has a central bore (38) within which mounting shaft (40), extending from the handle, is housed. Each end of the handle (14) has a camming surface (54) which engages a pivot pin (16) carried by the housing as the handle (14) is pivoted while inserting the mo-dule (4) into and withdrawing the module from the housing. This engagement of the camming surfaces (54) and the pivot pins (16) causes the handle ends and the associated mounting shafts to push radially against the elastomeric sleeves (30) as the handle is pivoted during insertion and extraction. The elastomeric sleeves (30) both support the mounting shafts and provide the desired biasing force to help keep the module (4) fully inserted within the housing (6).

Abstract: COMPUTER INTEGRATED MANUFACTURING  REWORK APPARATUS AND METHOD                    ABSTRACT    A manufacturing rework station is integrated with a computer.   A repair cell program running on the computer functions  as  an  interface  between  the  rework  station operator, one or more databases, and one or more knowledge bases.  The repair cell provides the operator with an easy to use graphical environment which aids in the diagnosis and repair  of  defects.   The  cell  simultaneously  provides operator assistance, records operator activity, and collects new knowledge when the problem under analysis was previously unknown.   The databases contain manufacturing history for each individual article.  The operator will input the serial number of the article with a bar-code reader,  causing the program to fetch the record of the article.  The computer generates an image article on the display.  The operator may select  a component of the  article with  a  lightpen.   In response  to  the  selection  of  a  component,  the  computer displays  the  possible  diagnoses   and  repair  actions associated with that component,  together with a figure of merit.  The operator may also invoke an expert consolation mode, in which the computer suggests a diagnosis or requests additional  information while  searching a directed graph. When a diagnosis is made, the computer automatically updates its databases.  A plant monitoring and reporting program has access to the diagnostic  statistics, and can generate  a warning  when  a  particular  defect  exceeds  a  limit,  or generate defect reports on request.
